Dorney Lake Duathlon

Dorney Lake Duathlon, hosted by RunThrough UK, takes place at the Dorney Lake Olympic venue in Windsor, UK. The event offers multiple distances: Super Sprint Duathlon (2.5k run, 10k bike, 2.5k run), Sprint Duathlon (5k run, 19k bike, 2.5k run), and Standard Duathlon (10k run, 37k bike, 5k run), plus relay options for teams. The flat, scenic grounds provide a totally flat bike and run course, ideal for fast times.
